EMERGENCY MECHANISM FOR MOTORS.

Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed July 6, 1914. Serial N 0. 849,155.

To all whom it may concern:

Be it known that we, HENRY A. CARPEN- TER and ARTHUR W. WARNER, citizensof the United States, residing at Sewickley, 1n the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Emergency Mechanism for Motors, &c., of which thefollowing is a specification.

The prime object of our invention is to provide simple and efficientemergency mechanism designed to cooperate wlth a motor or a motoractuated member, for operating the motor or the motor actuated memberunder abnormal conditions. The motor actuated member may, for example,be a revoluble shaft adapted to be employed for imparting a forward andback movement to a carrying element, said shaft bea charging anddischarging machine with our invention appliedthereto, and a portion ofa gas-bench having a retort therein; Fig. 2 is a vertical sectional Viewpart cularly showing the emergency mechanism and the manner ofconnecting same with the motor driven shaft; Fig. 3 is a sectional viewtaken on line III-III of Fig. 2; and Fig. 4 is a detail view of ashifting shaft operating means.

Referring to the drawlngs, 1 designates a charging and dischargingmachine designed to move along the front face of a stack of benches of acarbonization plant. A portion of the stack of benches is indicated bythe numeral 2. In a machine of the character illustrated, coal to becharged into the respective retorts is carried at the upper portion ofthe machine and is fed downwardly from the coal carrying-bin through atelescopic chute 3 into, as illustrated, a

combined charger and discharger- 4, whereby the coal is introduced tothe retorts and the coke discharged therefrom.

As illustrated and as preferred, the commotor 6 coupled up therewith bya plnion 7 and a gear wheel 8, the latter mounted on an end of the shaft5. As shown, 6 designates an electric motor, and this is the form ofmotor we preferably employ for normally actuating the shaft 5. The gearmentioned, as well as a bearing 9 for shaft 5, are located in a casingor housing 10secured to the housing of the motor, as particularly shownby Fig. 3.

As illustrated, shaft 5 is provided with engaging means in the form of agear 11, the function of which is to engage a coacting element of theemergency mechanism.

In'the form of our application as illustrated, the shaft 5 is screwthreaded as indicated at 12, and is designed to cause a for ward andbackward travel on said shaft of the fuel containing member 4, whichmember 4 is designed to contain a charge of fuel to be introduced into aretort of the gas bench.

The emergency mechanism, as illustrated and as preferred, is inclosed ina casing or housing 13 designed to be carried upon the charging anddischarging machine in close proximity to the electric motor 6 and itshousing. As shown, the emergency mechanism includes a verticallydisposed shaft 14 designed to be manually operated by a hand wheel 15located at one endof the shaft 14. The opposite end of the shaft 14 isprovided with a bevel pinion 16 designed to articulate with a bevel gearwheel 17.

Gear wheel 17 is mounted on an inclined shiftable shaft 18 and keyedthereto in amanner permitting axial motion of shaft 18 with respect tothe gear 17. Inclined shaft 18 is provided at its upper end with aclutch member 19 designed to cooperate with a clutch member 20 disposedon one end of a shaft 21, said shaft 21 at its opposite end is providedwith a pinion 22 adapted to coact with the gear 11 on'the motor drivenshaft 5.

For the purpose of moving shaft 18 and its clutch member 19, weprovide afoot operated lever 23 located on a platform 24 of the charging machine,said lever 23 being contar nected with the lower end of shaft 18 bymeans of a link connection 25. It will be evident that by bearing downupon the pedal of lever 23, the operator will cause shaft 18 to be movedupwardly and its clutch member 19 to engage with member 20. lVhen inthis shifted position, the shaft 1 1 is operated by hand wheel 15, andthis movement will revolve the shafts 18, 21 and pinion 22, which inturn will revolve the motor driven shaft 5, either to the right or tothe left as desired.

The actuating mechanism for shifting the shaft 18 and the clutch membersinto and out of engagement is provided with a weight 26 to assure thereturn movement of shaft 18 after pressure on the pedal of lever 23 isremoved.

As will be seen, that portion of the emergency mechanism located inadvance of the coupling 20 is normally inactive, in addition to Which,the gearing and mechanism intermediate the wheel 15 and shaft 5 is soarranged as to provide a reduction of speed toward the shaft with acorresponding increase in power when wheel 15 is moved manually; also,that the operating parts liable to have their operation affected byclogging through deposit of dust, etc., is entirely inclosed. Thesefeatures are of especial advantage in connection with an installation incharging and discharging apparatus such as hereinbefore referred to, inthe operation of which it is desirable that the length of time Withinwhich the fuel carrier may remain in the retort be limited by reason ofthe high temperature of the retort. Should the normal move ments of thefuel carrier, under the action of the motor, be affected in any manner,the operator has at his command an arrange ment of parts so connected upto the shaft as will permit him to provide movement to the shaftsuflicient to overcome the abnormal conditions which caused thestoppage, the length of time of operation of the emergency mechanismbeing dependent upon the character of the abnormal condition, theconnection at the coupling 20 being entirely under control of theoperator so that in cases where the abnormal condition is overcome andthe parts are free to be operated solely by the motor, the clutch willbe disengaged and the shaft operated by the motor alone.

What we claim is 1. In combination, a workperforming shaft, a motor,operative connections between the motor and shaft for driving thelatter, cooperating gears permanently movable with the shaft, said gearsbeing independent of said connections, a casing for said gears andconnections, and a normally inactive manually-operated emergencymechanism movable into and out of operative connection with said gearsat will for revolving said shaft.

2.
